diagnosing 9160 crash due to hardware error

[paul_tanner]

I have a working (hand-wired) prototype that connects to the internet without any problem.

Now I have made a PCB to replicate the same thing and loaded the same software.

Evidently there is a wiring error because the application crashes to the point where connection is made (lte_ready event).

Just before it crashes I get "E: Could not get GPIO Device Binding"

I am looking for the source of this error but cannot find it. (I test each GPIO binding before trying to activate LTE.)

Any suggestions as to where I might look?

Hello, 

Do you get any more errors along with that text? Are you able to share more information on your issue? Searching the NCS code base I find this error is returned when calling device_get_binding() in board.c of e.g. zephyr\boards\arm\actinius_icarus\board.c

What NCS version are you running? Have you had a schematic review of your board? Ensured that all soldering points are properly soldered? Please make sure that your devicetree is configured correctly.

Kind regards,
Øyvind
